Geosystems as an alternative to conventional coastal defense

Abstract

In recent decades, the increase in population on the coast, growth of erosion in many coastal stretches and the sea level rise, due to climate change, have led governments to invest more in protecting the coast. Geosystems have been shown as an alternative to conventional coastal structures because of cost reduction, efficiency of construction and speed of implementation. However this alternative leads to increase knowledge in their behavior, design and durability by the lack of suitable materials to withstand large storms, high diversity of non-standard methods or techniques and ease of degradation by vandalism.

“…Geotextile tube can be used for coastal and shore protection, forming embankments, jetties, breakwaters, artificial reefs, slope buttressing and temporary protection dykes [1][2][3]. Sand is conventionally the preferred infill material of geotextile tubes (geotubes) to construct a stable containment bund.…”
